FeBr₃ + H₂O = Fe(OH)Br₂ + HBr
Fe³⁺ + 3Br⁻ + H₂O = Fe(OH)²⁺ + 2Br⁻ + H⁺ + Br⁻
Fe³⁺ + H₂O = Fe(OH)²⁺ + H⁺
Fe(OH)Br + H₂O = Fe(OH)₂Br + HBr
Fe(OH)⁺ + 2Br⁻+ H₂O = Fe(OH)₂⁺ + Br⁻ + H⁺ + Br⁻
Fe(OH)⁺ + H₂O = Fe(OH)₂⁺ + H⁺
Fe(OH)₂Br + H₂O = Fe(OH)₃ + HBr
Fe(OH)₂⁺ + Br⁻ + H₂O = Fe(OH)₃ + H⁺ + Br⁻
Fe(OH)₂⁺ + H₂O = Fe(OH)₃ + H⁺
